Self-organization of matter is essential for natural pattern formation, chemical synthesis, as well as modern material science. Here we show that isovolumetric reactions of a single organometallic precursor allow symmetry breaking events from iron nuclei to the creation of different symmetric carbon structures: microspheres, nanotubes, and mirrored spiraling microcones. A mathematical model, based on mass conservation and chemical composition, quantitatively explains the shape growth. The genesis of such could have significant implications for material design.
物质的自组织对于自然形态形成、化学合成以及现代材料科学都是至关重要的。在这里,我们展示了单一有机金属前体的等容反应可以打破铁核的对称性,从而创造出不同对称的碳结构:微球、纳米管和镜像螺旋微锥。一个基于质量守恒和化学成分的数学模型定量解释了形状的生长。这种自组织的起源可能对材料设计有重大影响。
